Tow'aZZ whom t may concern Be it known that we, FRANK AsnwomH Hour, asubject of the King of the United Kingdom of Great Britain and Ireland,and resident of Noon Sun House, Whitworth Road, Rochdale. in the countyof Lancaster, England, and Gnrnnnon limsi-mw, a subject of the King ofthe United Kingdom of Great Britain and Ireland, and resident of G2Market street, I'Vhitworth, in the county of Lancaster, England, haveinvented new and useful Improvements in lVindingellIac hines, of whichthe following is a specification.

'.Ihis invention relates to winding machines of any kind in which a rollkept revolif'ing isemployed to revolve a winding` holder by frictionagainst such holder vor a conical or cylindrical spool placed upon it or'yarn or thread wound thereon and provision is made for the holder orspool or yarn or thread wound thereon to be withdrawn as there may beoccasion, by hand o1' automatically, out of Contact with the roll as forinstance when a yarn or thread being wound into a package of any kindsuch for example as a cheese or cop or the likeV breaks or comes to anend and the broken end or termination has to be found and pieced orthepackage attains the size fresh spool is to be applied to the spindle andto have yarn or thread brought to it.

This invention consists in a simple and efficient device insuring that,once removed :from contact with the roll by hand or by the operation ofstop mechanism, a holder or spool or completed yarn package shall besecurely held against return toward or against the roll under theinfluence of vibration or other accidentalv cause and until some personperforms the proper movements for permitting the return of the holder orspool or yarn thereon toward or against the roll, the object of theinvention being to guard completely against continued rollingV of yarnor thread upon the roll and chaling or polishing or other damage to theyarn or thread thereby, damage to the holder or roll or both by theholder falling against the roll and hindrance to the finding and piecingof a broken yarn or thread or the removal of a completed package or theapplication of an empty spool to the holder and the attachment of yarnor thread to such spool or other preparation for the winding of a freshpackage.

Othenparts of theinvention are pointed out hereinafter and in the claimsfollowing.

In the accompanying drawings in which the same letters and numeralsindicate corresponding parts in all the figures, illustrativeembodiments of this invention are shown.

In the drawings, Figure l is a front eleyation of part of a windingmachine, showing one winding head, Fig. Q is a plan of part of a.winding machine showing parts of two winding heads and one cam servingfor working the traversing thread guides of both heads. Fig. 3 is a sideelevation partly in vertical section through part of a winding machineand shows one winding head in side elevation. Some of the parts shown inFigs. l, 9. and 3 are shown in only one or two of such figures andomitted from the others or other so that other parts may be shown moreclearly. Fig. 4 is a side elevation partly in vertical section showingon a larger scale a pawl shown in Fig. 3 and parts carrying and usedwith it. Figs. 5 and 6 are respectively a front and side elevation drawnon a larger scale than Figs. 1, 2 and 3 and showing a traversing threadguide. Figs. 7 and 8 are respectively a side view and end view of a dieused with a traversing guide.

In the drawings many of the parts shown are of well known constructionbeing very similar to parts shown in the drawings of United StatesLetters Patent No. 952,015, dated March th 1910 granted to JohnOlipliant McKean and will be described herein in so far as is convenientto facilitate the description of the parts provided according to thisinvention but it is to be understood that the parts provided accordingto this invention are applicable to winding machines of other kinds inwhich they may be desirable.

In the drawings a is a holder of ordinary construction to receive aconical tube or shell 7) on which a package of yarn or thread may bewound. c is a driving roll mounted fast upon a. shaft (Z extendinglengthwise of the machine and revolved in brackets d1 by any suitablemeans. c1 is a collar loose upon the roll to obviate undue friction uponthe smaller end of a conical package being wound. e is a cam mountedfast upon a shaft f extending lengthwise of the machine SMS arrow A overthe pawl s and revolved by any suitable means shown as provided withthree cam tracks g 7L 72, formed as grooves 1n a way usual to work twothread guides c' one at each side of the use in moving the holder c fromor con- Y r toward or for holding the holder c away from the drivingroll c. As in machines already known the rod Zis made to pass through a,slot n in an arm o mounted on the same pivots p as the lever frame orapron g of the stop motion and furnished with lugs 7' embracing thatlever frame or apron g at one side but for the purpose of this inventionthe slot 'n is formed sopas to allow an upward movement of the rod Zlimited as will be hereinafter described. Further for the purpose ofthis invention a pawl s to engage the rack m of the rod Z and whenengaged with it to raise the rod Z against the upper end of the slot nis pivoted in the arm o. In the case illustrated the pawl s Iis pivotedto the arm o by means of the pin Z. The arm is formed so as to providebelow the slot n a surface u against which the pawl s may rest in itsordinary position with the rack m of the rod Z resting on it so that therod Z may be pulled or pushed in the direction indicated by the and therod Z if raised clear of the pawl s may be pulled forward or pushedbackward through the slot n to raise or lower the holder c. The slot nis made of such height that so long as`the rack m of the rod Z is in theslot n and over the pawl s, the pawl s can not be turned past the rack'm in a clockwise direction as viewed in Figs. 3 and 4 and a slightmovement of the pawl s about its pivot t in such clockwisedirectionwhile in engagement with the rack m will press the rod Zagainst the upper end of the slot n. A projection (Z2 indicated bydotted lines in the adjacent bracket Z1 forms a stop against which theinclined part of the rod Z may arrive in order that the forward movementof the rod Z and the lifting of the holder a may be limited.

' u is an arm mounted on 'a shaft w made to oscillate in the well-knownmanner to move the apron or lever frame g in order to raise the holdera.

For simplicity description will be given of the means for supporting andguiding one trolling its return Y j ustable stop 3 thread guide thoughany number of similar means may be provided in accordance with thenumber of winding heads in a machine. 1 In the construction illustrated'in the drawings, guide bars li/'tosupport and guide movement are mountedon a frame .a withV arms lV to embrace the studs p on which the leverframe or apron y of the stop motion and the arm 0 are pivoted and withan arm 2 extending downward to carry an ada spring iattached at itsother end to a bracket 5 secured bythe bolt G and the nut thereon to arail j7 forming part of the framework of the machine. The VframesJ ismovable about the studs y) independently of the lever frameor apron gand ordinarily the spring l which is in tension holdsfthe adjustablestop 3 which is shown as a setscrew against t-he rail 7 in ordertodetermine the position of the frame .e and the path of the thread guidez' but leaves theiframe .a

free to be moved about the studs yi'in the direction indicated by thearrow B when Vthe thread guide c' is to'be disconnected from the cam e.The guide bara1 is shown as of rectangular transverse section andadapted to be secured at each end to the frame e by screws 8 which alsoserve to hold in grooves in the frame socket plates 9 with conicalsockets 10 in which the guide bar g/ which is in the form of acylindrical rod having conical ends to be inserted in the sockets 10, ismounted. rlhe frame e and socket plates 9 are so formed that the guidebars g/ are the thread guide z' in its traversing and to receiveconnection of parallel to one another and to the axis of the drivingroll c. The thread guide which is provided in the usual way withja notchl1 for guiding yarn is provided'with a tubular part l2 yto surround andto'be slid upon the guide bar 'y and with a forked partrl to embrace andto be slid upon the guide bar an and the thread guide z' is fitted tothe guide bars m y. so as to be guided thereon with suiiicient accuracybut also to be movable along them with suflicient freedom. The thread.guide z' is provided with two sockets 14, in one or other of which adie 16 provided with a cylindrical shank 17 to fit the sockets towardeach end to be engaged with a cam track of the cam e may be pivoted. Theshank 17 of the die 16is inserted in the socket 14 when it is to beengaged with the central cam track g of the cam e for a cylindricalpackage to be wound and in the socket 15 when it is to be engaged in theadjacent right hand track z, of the cam e Vfor a conical package to bewound. The sockets 14, 15 are formed in such positions relatively to theguide notch 11 that when the die 16 is in the socket 14 and engaged withthe adjacent right hand cam track 71, for the winding of a conicalpackage the guide notch l1 shall be 14., 15 and a shoe 18 tapering 'Ytraveised to and fro in a path in proper po sition relatively to theroll c and holder a or a conical package thereon and that when the die16 is in the socket 15 and engaged with the cain track g for the windingof a cylindrical package the guide notch 11 shall be traversed to andfro in a path still in proper position relatively to the roll c and theholder 19 or cylindrical package upon it.

As the holder a is raised byyarn or thread being wound around it in theordinary way the rod Z will be pushed forward over the pawl s tooth bytooth in the direction indicated by the arrow A, the rack m alwaysresting in engagement with the pawl s unless disengaged by some personraising the handle Zhen the stop mechanism ot the machine is actuated tostop winding either through a package attaining the diameter desired orh v a thread breaking or coming to an end the lever 'trame or apron qbeing turned by the arm 0 about its pivot j) in the direction indicatedby the ari'ow B will cause the pawl s to engage the rack m and to beturned about its pivot Z by suoli rack m and made to press the rod Zagainst the top of the slot a whereupon the continued movement of thelever frame or apron q will pull forward the rod Z in the directionindicated by the arrow A and raise the holder (t. So long as theweightof the holder a is borne by the pawl s the rod Z will hold thepawl s turned so far as it can be in the clockwise direction and will beheld thereby against the top of the slot a so that the escape of therack lm, and the pawl s from one another under the influence ofvibration of the. machine is guarded against and the holder a being onceraised by the action of the stop motion can not be lowered again withoutthe attention of some person for the purpose oit' lowering` it. lt theaction of the stop motion raising the holder c be brought about by thebreakage or ending o a thread being wound the restoration of the leverframe or apron q to its ordinary position in the known way will lowerthe holder o for winding to proceed without it being necessary for therack m of the rod Z to be disengaged from the pawl s. In order to lowerthe holder a after it has been raised by the action of the stopmechanism brought about by a. package attaining the diameter desired therod Z inust be disengaged from the pawl. s and the disengagement may beeffected by the rod Z being pulled forward by means of the handle Z2 sothat the rack m is ma de to release the pawl s1 which then falling backagainst the surface u will allow the rod Z to be pushed or allowed tomove backward to lower the holder a provided that the rod Z is raised sothat the teeth of the rack m are held clear of the pawl s. Accidentaldisen gagement of the rack fm, from the pawl s is practically impossibleand so accidental descent of the holder a is guarded againsteffectually. The holder a may be raised and lowered at any time in thecourse of the winding of a package by a person moving the handle 7c itthe rack m be raised and kept clear of the pawl s and the rod Z has notbeen moved into the position then occupied by it through the action ofthe stop inechanism.

The operation, use and function ot the or cylindrical packages are to bewound will also work similarly to the like parts of maw chinos of theusual construction and arrangement. `Whcn change is to be made Jfrom orto the winding oit a cylindrical package to or from the winding ot' aconical package the changes requisite of either of the holders a and 19for the other and the tubes or the like on which yarn is to be wound aremade in the ordinary way and the frame .a is moved about the pivots 7?in the direction indicated by the arrow B so that the thread guide iswithdrawn so far from the cam c that the die 1G can be disengaged fromthe cani track g or ZL in which it may be at the time and when the l@thread guide 'Z being pushed along the bars fc 1 1/ to a convenientposition the die 16 is moved from the one socket 14 or 15 to the otherand then the die 16 is brought opposite to the other cam track h or gand is brought into engagement therewith by the.

'frame being allowed to be moved back by the spring i and then windingmay proceed. The change of the die 1G from one of the sockets 1st, 15 tothe other and from the central cam track f/ to the adjacent right handcam track ZL or the reverse change is thus accomplished without anyother part than the die 16 being dismounted from the machine and theframe e being simply moved from and allowed to be moved by the spring 4back to the position determined by the adjustable stop 3 the guide bars:c lQ/ are always brought back automatically into proper position `forwinding to proceed. ln

the constructions hitherto provided the change from or to the winding ofcylindrical packages to or from the winding of conical packages has beeneffected by the change Y of thread guides and has involved thedismouiiting of one or more of the guide bars or other parts on or inwhich the thread guides are mounted for use and in the dismounting ofsuch parts there has been involved the practical impossibility of putiV"through the said space ting them back accurately into their previouspositions. The die 16 having a cylindrical shank and the sockets 14:, l5to receive it being cylindrical the removal of the `die 16 from one ofthe sockets 1li, l5 to the other and its restoration to the socket inwhich it may first have been placed for use, involves no possibility ofderangement of adjustments.

We would have it clearly understood that changes may be made within thescope of the invention as indicated in the claims.

What we do claim as our invention and desire to secure by Letters Patentis l. In a winding machine, a driving roll, a helder' whereon materialmay be wound adapted to cooperate with the driving roll so that windingis effected by friction, means for supporting such'holder and enablingit to be moved toward and away from the driving roll, a link for movingsuch holder connccted to said means and furnished with a handle, Va stopmotion comprising a part with a space through which the said link ispassed allowing limited movement of such link in the direction of thelength of the siace an engaofinv device Jivoted in such` 7 2D D part toiorm a rest for and to engage the link and movable thereby to bring suchlink against one end ol' the"said space and allowing the link whendisengaged from the engaging means to be pushed or pulled whereby thesaid holder when moved away from the driving roll by the stop mechanismis prevented irom being accidentally moved again toward it,substantially as hereinbefore described.
